Abstract

Introduction: Dental anxiety is a distressing challenge faced by both the patients and the dental care provider, particularly in the Department of Orthodontics. The goal of this study was to assess the effect of aromatherapy (oils) on dental anxiety level among orthodontic patients and to compare the effect on anxiety levels between lavender oil, rose oil, and a placebo.

Materials and methods: A total of 72 patients (36 men and 36 women) who reported to the Department of Orthodontics were selected and randomly allocated into three groups: lavender oil, rose oil, and placebo. The ambient odor of those oils or placebo was maintained with a candle warmer, and the patients were made to wait in their respective rooms for 15 minutes. Participants' heart rate and blood pressure, being reliable and objective indicators of anxiety, were measured using pulse oximeter and sphygmomanometer, respectively. Additionally, a questionnaire, comprising demographic data and questions representing a modified Dental Anxiety Scale, was given to the patients to measure subjective anxiety levels before and after aromatic therapy. Paired t-test, analysis of variance, and the Wilcoxon signed-rank test were used for both subjective and objective analyses.

Results: Lavender oil and rose oil produced a significant reduction of dental anxiety level among orthodontic patients in both objective and subjective method (P ≤ .05); lavender oil demonstrated a greater significance in reducing the anxiety level when compared to rose oil.

Conclusion: Our findings indicate that aromatherapy offers promising effect against dental anxiety among orthodontic patients. Aromatherapy can be recommended as an easy alternative to reduce anxiety in patients before orthodontic treatment.
